Chayn, which means 'peace of mind' in Urdu, brings together crowdsourced information from volunteers around the world and in five years has reached more than 200,000 users.
Chayn is staffed by hundreds of volunteers, most of whom are survivors of domestic abuse.
Hera, 28, said: "I set up Chayn after I helped two friends of mine get out of abusive marriages, one in the UK and one in Pakistan.
In a letter to Hera, Theresa May wrote: "Your work with 'Chayn' is providing vital support and information to hundreds of thousands of women across the world experiencing domestic violence.
Hera has also recently been named on the Forbes magazine's prestigious 30 Under 30 list for social entrepreneurs and the MIT innovators under 35 for her work on Chayn. And earlier this month she won a Microsoft Spark Award, which recognizes an individual who is 'driving positive change that impacts the way we live and work.' Hera spent some of her school days in Altrincham, when her father came to Greater Manchester to work as a doctor, before her family moved to Lahore in Pakistan.
Hera plans further developments for the Chayn platform with new features including artificial intelligence, chatbots and use of social media platforms such as Snapchat, with most users currently accessing the service via Facebook.
Many of the women who turn to Chayn for advice are based in the UK and are seeking help to deal with manipulative partners who may seek to control their use of social media as part of their controlling behaviour.
Hera added: "Chayn has now reached more than 200,000 people in 12 countries - it is solving a real problem which people have."
